The BOR-4 provides four independent 2PDT relay interfaces with two optically isolated or 5-volt TTL/CMOS compatible inputs. Other unique features of the BOR-4 are the Programmable logic and pulse stretching (delays) from 500 MS (1/2 second) to 108 minutes. The BOR-4 is equipped with a single small profile aluminum chassis.
Features:
• Each 2PDT relay maybe configured with two independent 5 to 28 VDC optically isolated or 5 volt TTL/CMOS compatible inputs
• Logic functions include, sustained, toggle, set-reset (flip-flop), dual alternate action or failing/rising edge pulse
• Telephone line ring detection on relay 1
• The pulse stretcher or time delay may be user programmed from 500 MS (1/2 second) to 108 minutes
• All user programming is done with selection jumpers
